5 SHEETS-SHEET 4- In the preferred construction the observ-V inginstrument comprises a lens so mounted as to projectan image of-'fthetarget-lon screen of ground glass or the like. The lens and screen maybe arranged so ias""t'o"'be relatively adjustable for focusing purposesbut-they Vare otherwise disposed in such fined relation that when trulypointed ator laid on the target the image vof Vthe latter will ap-` pearon the screen in coincidence with a centralmark onrthe screen. The wholedevice is so movably mounted on a suitable tripodor 'other stand that itbe laid on theltarget and readily clamped orxed when inthe desiredYposition for commencing the observations. To facilitate the initialaiming of the device it may be provided with a pair of sights of somesuitabletype which constitute a line of sight p 'arallelvto that passingthrough the center vof the lens and the central mark on'tlie screen.'V A`seriesof concentric circles are drawn about thecenter markthe circlesbeinfr equidistant or otherwise .ar-V

ranged as desired. A pointer ora markA of some'convenient typeO carriedby an arm or otherwise is so mounted thatit can be moved in anydirection over the surface of the screen. Conveniently this pointer ormark is arranged to be movable'in twodirections at Vright angles to eachother by means of screws with milled heads or hand wheels. Y For eX-ample, a pointer arm may be carried by a saddle or the like whichengagesa screwthreaded spindle mounted for instance horizontally insuitable bearingsVY infa VVframe. The latter is arranged toA slide inavertical direction .in an outer frame and at right an-V gles to the axisof the screwlthreaded horizfontal spindle. 'Ihe vertical slidingv ofthis spindle with the pointer Vin the outer frame may be effected bymeans Aof a screwthreaded shaft which engages a sleeve or nut carried bythesliding frame in which the horizontal,spindleismounted; j' 7 Theinstrument'is used in thefollowing way. In the rst place the device` isdirected at the target the imageef which is. brought into coincidencewitlithe central `mark onthe screen and` at, a 'suitable moment l.thelens'l and screen are fixed.' By Vnfieans ofthe milled heads or theQlike and Vjscrew-threadedv rods the pointer or movable markfis causedto Vfollow the target image on the screen for a convenient interval`ottime which may be` equal to they time of flight ofthe projectile'when red from the gun at the range ofthe target. Alternatively this timeof observation may be Ysome convenientv fraction of the-time of tlighftwhen by meansA of the circles on the the-direction of travel."

screen it isfpossible to set the pointer so as to show on the screen thedistance traveled by thetarget in theltimeofkliight as well as Byjmeansof the connecting mechanism hereinafter" described vthese movements ofthe Vpointerwill" have lcaused corresponding movements of the gun sightor sights so that if the gun is laid by l' these adjusted sights andVfired litwill have the necessary lead to insure the hitting of thetarget.

If a single gun sight is employed this is mounted-'for example so thatit can slide or rock verticallyin ya frame which in turn is Jarranged soto be Ycapable of sliding or rocking horizontally on a bed which canitcself be moved so as to give the sight as a whole the necessaryadjustments for range and deflection. The bed is suitably formed andgraduated to enable these adjustments to `be mad/e,Y The yertical andhorizontal movements of the .sight may ber brought about in various w(ys as for instance by means of screw-threadedV `rods which Iare rotatedby sliding racks each engaging a Vpinion carried by a rod or the lsightand frame may each be directly pushed or drawn in either direction.Where two sights are 'used' each is'mountedon a bed which is so Aformedas tov be adjustable for range and de- Flection.V One sight is somounted that it cdan'be moved vertically on its bed while the other isarranged so' as to be movable horizontally on its bed.V Each'of thesesights is conveniently in the form ol or comprises a slit or wire oris'fotherwise constructed so that it can be readily keptpon the targetin spite of'movement ofthe gun in a direction Y other than that which'isintended to beregulated by means of that s ight. Thus the sight l'whichis adjustable horizontally vhas a4verticalf viewing slit or theflikeiVwhile the vertically adjustable sightfhas 'a horizontal slit Vor `wire.Whether Vsingle or double sights lare used these may each bel of anyconvenient known type either open or otherwise or ink telescopic form.
